Pwodwi ki baze sou TDI-polyester- ak yon kontni TDI gratis ki ba anpil (tipikman mwens pase 0.1%).
Sa a lakòz yon sistèm an poliyiretàn ki pa-toksik epi li diminye danje pwosesis yo. Li ofri pi ba viskozite, pi long lavi po, ak pi vit demoulding. Konpatibilite li ak yon seri de guérison pèmèt pwodiktivite segondè. Elastomè ki kapab lakòz la montre bon rezistans abrasion, seri konpresyon, fòs chire, ak pwopriyete dinamik.

Viskozite ki ba.
Ekselan pèfòmans dinamik.
Tan opere long.
Segondè kapasite pote.
Tan lage a kout.
Amelyore pèfòmans tanperati ki wo.
